Set the Setting Firefox from About: Config

One of the best things of Firefox is the flexibility and the ekstenbility. To access the internals of Firefox, open the page about: config

If you are just regular Firefox user, then you may not be familiar with the about: config. Page about: config Firefox does not look like a normal page because it contains hidden configuration. He is quite powerful because it is hidden and not simply as a normal Preferences window. On page about: config, you need to know what the right or you can make everything topsy.

At the time the first time open page about: config, you should receive an approval (which is actually just a warning) before proceeding. You will see a list of Firefox configuration items. Configuration that has been modified by the user with a bold set of user status. Many of the options in the configuration during installation, but you can change them as you wish.

When I open the configuration page you will see a box filter which can be used to search for specific items. This makes the search items so much easier than the need to roll up-roll is a long list. To use the Filter, type all or part of the name of the item in the box and then press [Enter]
The items displayed by about: config

When I open the page about: config, you will see a column Preference Name, Status, Type, and Value. Preference Name displays the name of the item, the item's status display (Firefox will change it to the user if the value is set has been changed by the user), Type displays the type of data items, and display the value of Value items - when editing an item, you will only edit the value of their each option. Almost all items can be modified. Item can be a boolean value, integer, or string. You can also add items to about: config.

Most easy way to get to know the configuration used by the browser is to change the Existing items. That there is a setting on the Tools menu, Options can also be configured from the about: config. For example, let us change the Start page of the about: config to point to http://www.google.com

First, open about: config, and then when the startup on the Filter box and then press [Enter]. Firefox will display all the items on the name there is the word "startup". Items for the home is browser.startup.homepage. To change it to Google's site, double-click the item and the dialog box that appears, type http://www.google.com, and then click OK

Some changes take effect immediately, such as homepage, but some other changes may require you to restart Firefox. Firefox will not advise whether you need to do a restart or not to apply the changes. Now that know the tool to edit the configuration we can start to set up Firefox. Do not forget that there are many settings in here and need to diwaspadai some settings that can make the behavior of Firefox to be unexpected.

Speed up Firefox

Pipelining in the box type filter. Network.http.pipelining to change the value to true, and network.http.pipelining.maxrequests to increase the value to 8. Now type the max-conections increase in value to 96, and for network.http.max-connections-per-server value up to 32

Disable Antivirus Scanning

This version only for Windows. If you download large files, the process of scanning can be slow. Because later you will also scan all downloaded files, you may need to men-disable it. However, if you have a paranoid nature you might not need to work this part especial. To men-disable antivirus scanning, type in the box scanwhendone filter. Change the value to false browser.download.manager.scanWhenDone

Opens Popup Javascript For Tab

If you want to open all windows, including popups, as a new tab, you have to tell Firefox's about: config. Type in the box Newwindow Filter. Browser.link.open_newwindow.restriction Change the value to 0 (zero)

Check Spelling in All Text Box

By default, Firefox only checks spelling in the text box and consists of several lines. You can set Firefox to check spelling in all text boxes. Type spellcheckdefault on the box filters. Change the value of 2 to layout.spellcheckDefault

Opening the Search Results in New Tab Bar

When using the Search Bar, the results shown in the active tab. This can be because you want to disrupt the opening page of the place where you are now. So that Firefox always open search results in new tab, type in the box openintab Filter. Change the value to true browser.search.openintab

Automatically Export Bookmark

On Firefox 3, bookmarks are stored and automatically exported for you. The problem is they are saved by default as place.sqlite, not in html format is more flexible. To change the settings so that the bookmarks can be easily imported back, type in the box autoexporthtml Filter. Change the value to true browser.bookmarks.autoExportHTML.

Disable Delay Time When Installing the extension

One complaint about Firefox is a countdown that you must wait every time would install an extension. Fortunately, this can be disable. Type enable_delay on the box filters. Change security.dialog_enable_delay to 0 (zero)

View Source Code in External Editor

When you want to see the source code of a page, Firefox opens a popup window. Most developers may want to open them in their favorite editors from having to copy-paste. To do so, there are two entries that should be changed. Type view_source.editor. View_source.editor.external to change the value to true, and for the values view_source.editor.path enter the path to the editor of your choice.

Getting Search Results Add-on that more.

When performing a search in the Add-ons window, you will only see the top five results. You may find it more efficient if the amount more. Type getaddons on the box filters. Increase the value extension.getAddons.maxResults to 10 (or higher, if you want to see more)

Set the Backspace key

Know if you can configure Firefox to use the Backspace key to return to the previous page or forward to the next page. Thus, you do not have to move back and forth from keyboard to mouse. Backspace in the box type filter. Browser.backspace_action Change the value to 0 (zero) to the previous page, or 1 for the next page.

Some Startup Homepage

We can use the Firefox tab browsing ability to open multiple browser homepage when opened or when the Home button is clicked. To open some of the homepage, enter the URL of the page you want to open on browser.startup.homepage, separated with a straight line (l) As an example here, we enter http://www.mozilla.com l http://www.google. com l http://www.youtube.com Firefox will open the three-tab when you run.

When off the box Confirm Closing Browser

Change the Start page is an example that is easy; there are many options that are far more complex here. When viewing the list, you can find out functions of an item's name. From our previous example, browser.startup.homepage contains pages that are loaded when the browser in the run.

Another example is browser.tabs.warnOnClose. This item serves to turn or off the confirmation dialog box that appears when closing the browser with multiple tabs. By default, Firefox will ask for confirmation when you close the window that contains several tabs. From about: config you can be off

Note that in the city there is a check dialog box you can check that Firefox ask a confirmation before you close the window with several tabs. Firefox will not ask for confirmation if the check box is not checked () or when browser.tabs.warnOnClose status is set to false.

Other Settig

About: config settings also contain that are not always immediately seen by the user. There are options to set the scrolling mouse wheel, the path to an external editor that is used by Firefox, or even set a password expiration; all settings and more can be edited by user

Many third-party extension mebuat to the new entry in the about: config. Configuration can also be changed. You can experiment if you want, but, for the extension of third parties, it's good test and reset the items to change the default, make sure to keep functioning.

Tips

If Firefox becomes strange when you accidentally configure wrong about: config, you can improve it by doing one of the following:
• Create a back-up prefs.js file before editing started. Then, if something happens, you can improve it with the copy-file back-up to replace a corrupt file
• If it does not make a back-up prefs.js, you can close Firefox and run the command firefox-safe-mode from the Run dialog box to display the Firefox Safe Mode. Then, select the Reset all user preferences to Firefox defaults. Please note that all user settings will be restored to their default values.
